The Amphenol FCI BERGSTIK II 79821-114HLF is a 14-position dual-row male pin header in the board-to-board style, finished in black glass-filled polyester (UL94 V-0) with square phosphor-bronze contacts. The 0.100 inch (2.54 mm) pitch and push-pull push-pull fastening make it a standard-fit header across industrial automation and consumer electronics boards; the 5 A per contact rating at 110 V covers signal and low-power distribution without needing a heavier connector class. Gold or Gold GXT contact plating at 30 µin (0.76 µm) over the mating surface gives reliable repeat-mating performance in any application that sees field service.
What the ratings mean for your layout
Stack height and board fit
The 0.100 inch (2.54 mm) insulation height matches the pitch — the header sits flush with the board surface as a right-angle or vertical stand-off. The 0.200 inch (5.08 mm) tail length and 0.730 inch (18.54 mm) overall contact length give 0.430 inch (10.92 mm) of engagement depth on the mating side, which is ample for a confident mate in any shrouded or unshrouded socket. The unshrouded body means there is no polarisation rib — if your system needs keying you must use the housing variant or a polarized header in the series.
Sourcing and lifecycle
The 79821-114HLF is listed Active — quoted to order against the BOM quantity with no official successor. Position variants in the same series share the same footprint and pitch — if your circuit count changes, you can move between members without a board respin. Confirm the mating half pinout before committing.
